Tank
The tank did not play any major role in WWI, although, in WWII it replaced almost all cavalry in modern war. The tank in WWI was used to get past the barbed wire that was set in front of enemy trenches. If the british were to make more tanks they would have been more significant in this war. The tank was almost like the Trojan Horse except the enemy didn't take the tank as an offering. The tank transported soldiers to enemy trenches.
